Utter nonsense. You cannot dump fuel on a TU5. If the problem is not that serious, you circle above the airfield to burn off fuel, in any other case you go in overweight. After a 1.5h flight and only 80something pax o/b the a/c would have been well under MLW (80t) even if it was fuelled for the return journey.
Amazing amount of ill-informed posts in the past 12 hours surfacing on this thread that started off reasonably sound.
Andrasz, you might have noted my very sceptical tone in my post. This thread is about sifting the wheat from the chaff, not attacking every poster who dares note a media rumour on Russian TV.
Your specific detail about the TU was very useful though so thanks for that.
